Answer 2

Answer:

As per the question

in 10% of w/w% solution

10 = 5/mass of solution(x) x 100

x = 100 x 5 ÷ 10

50 g

let water evaporated to make concentration 15% be x gram.

mass of solution = 50 - x

so , 15 = 5 / 50 - X x 100

x = 16.67 g

So the mass of water that should be evaporated = 16.67g
